In the PHOTOS app, when viewing a photo, if you tap the photo, you get the trashcan icon, the icon that allows you to UPLOAD, SHARE, etc.. How about a third icon that gives you info about the pict?

File name?
Pict Resolution?
Album Name
File size?
GPS Geotag info?
Etc
A Notes field would be great too, if possible.

Would that be so tough to do?
